Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives.

Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power.

Kim Jong-il Is Dead

The AP and others are reporting that North Korean leader Kim Jong-Il has died at the age of 70. This has long been expected, but what comes next is unclear.

That is unlikely, however. If a power struggle ensues, the North Korean people will be caught in the middle. The countries with the most at stake in the event of a complete collapse of the DPRK – especially South Korea and China – should take the lead in helping the North Koreans to sort out their future.
